Allow the setup to time out.
The incubator is now ready to communicate with
your computer.
Setting up the computer:
Your communications software will most likely have
a setup routine to set the parameters listed below.
These are the values the incubator is using, so
you must match your computers software
parameters accordingly. Also, you will probably
have to select the “COM” serial port you chose
when you connected the cable from your computer
to the incubator. The software may ask what format
the data is in. You should choose “ASCII”.

Baud Rate:
Baud Rate value selected
earlier in Step 1.
Parity:
None (0)
Data Bits:
Eight (8)

COM Port:
Selected by user
Format:
ASCII
Using the Communications:
The incubator transmits information on its RS232
Port as long as the status update time interval is
not “0.0.”
If you start your communication software with the
incubator on, most likely you will see the error(s)
messages as follows:
ERR
? VALUE IS READ ONLY
? ILLEGAL COMMAND
Wait for the Status Update Time duration you
selected to complete, and the communications will
correct itself.
Besides having the incubator transmit information
in one of the three formats, the user can monitor
other values or even change some of these from
their computer.
The following table lists the available commands
for monitoring or controlling your unit.
To View Data: If Status Update Time is “0.0” no
data will automatically be displayed. To view data
within a particular command code, type that
command code followed by the question mark (?)
symbol and then ENTER (Return).
